Today we learn via 9to5Mac that some carriers are already receiving special SIM cards for the new iPhone, which is expected to launch in stores on Sept. 21.

The next iPhone has long been rumored to use a "nano" SIM card that's much smaller than the one used in iPhones today. Nano SIM cards will allow the iPhone and other smartphones to be much thinner and lighter.

German blog iFun is reporting Telekom, T-Mobile's European-based carrier, started receiving nano SIM cards for "a new generation of SIM cards for the latest generation of smartphones that come in the near future on the market."
